What is indicated by the modifier XP?

The modifier XP signifies "Separate Practitioner." This modifier is used in the context of reporting services that are provided by different practitioners. In scenarios where multiple providers are involved in a patient's care, particularly when the services are related but delivered by distinct practitioners, XP indicates that the services performed are entirely separate and should be treated as such for billing purposes. This allows for appropriate reimbursement for each practitioner's services without confusion about who provided which part of the care.

In comparison, the other choices do not accurately reflect the meaning of XP. Extra Physician, Expanded Procedure, and Exclusive Practitioner do not align with the established definitions within the Current Procedural Terminology (CPT) modifier guidelines. Each of those terms implies a different concept that does not relate to the modifier XP's functionality and application in medical billing and coding practices.
